The initial rates as reported by a student participant are shown
in Table 3 where the concentration of KI is fixed at 0.100 M
and the concentration of H2O2 is varied from 0.00 to 1.88M. To
test the hypothesis that the order of reaction with respect toH2O2
is 1 (h = 1), a plot of initial rate (Δ[H2O2]/(2Δt)) vs H2O2
concentration is plotted; see Figure 2. Initial rate is directly
proportional to concentration with the equation
